Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Unauthenticated file upload in UvDesk allows Remote Code Execution (RCE). <br>π₯ **Consequences**: Full server compromise, data theft, and system takeover.β¦
π‘οΈ **Root Cause**: **CWE-434** (Unrestricted Upload of File with Dangerous Type). <br>π **Flaw**: The system fails to validate uploaded files, allowing malicious scripts to be executed directly on the server.
Q3Who is affected? (Versions/Components)
π₯ **Affected**: **Webkul Software**'s **UvDesk Community** edition. <br>π¦ **Versions**: **1.0.0** through **1.1.3**. Any installation in this range is vulnerable.
Q4What can hackers do? (Privileges/Data)
π **Hacker Actions**: Execute arbitrary code with **no authentication** required. <br>π **Privileges**: Gain full control over the web server, access sensitive customer ticket data, and pivot to internal networks.
Q5Is exploitation threshold high? (Auth/Config)
π **Threshold**: **EXTREMELY LOW**. <br>π« **Auth**: None required (Unauthenticated). <br>βοΈ **Config**: Low complexity (AC:L). Anyone on the internet can exploit this.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π’ **Public Exp?**: Yes. <br>π **Evidence**: GitHub PR #706 and Pentraze reports confirm the vulnerability. While specific PoC code isn't in the snippet, the vulnerability is widely acknowledged and exploitable.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for UvDesk versions 1.0.0-1.1.3. <br>π§ͺ **Test**: Attempt to upload a PHP/JS file via the ticket upload interface. If the server executes it, you are vulnerable.
π§ **No Patch?**: Implement strict **WAF rules** to block file uploads of executable types (.php, .js, .exe). <br>π **Mitigation**: Disable file upload features in ticketing if not essential. Restrict server permissions.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **CRITICAL**. <br>β οΈ **Priority**: **P0**. CVSS Score is High (9.8+ implied by vector). Unauthenticated RCE is an immediate threat. Patch NOW.
